Perhaps You have one Diametrically magnetised and one Axially magnetised then?
..... I am thinking the Seller on Aliexpress , just sends whatever 4mm or 6mm magnets they have handy..

Yep I agree with you Kbird. I have just checked all 4 magnets that came with boards and I have 3 normal and just 1 Diametrically magnetised magnet.
I have given up and ordered some 6x2.5mm Diametrically magnetised magnets from local Australian firm. Will be a little easier to handle as well. Cheers
